Sorry I didn't get that. O365 is configured to use CES for both Inbound and outbound mail traffic, and I can see these emails in Message tracking as "Delivered" but it end up in spam/junk mailbox of the user.

Thanks for you reply! I couldn't find X-Ironport-Antispam, X-IPAS-Result in the Message headers of the emails in spam/junk folder; I only can see Microsoft headers though. Similarly I can't find ESA's Anti-spam (CASE) verdicts in Message Tracking for those emails (I guess because the message has been delivered )

Hi there! We have a client who's his Office365 is configured to use Cisco Email Security (CES) for both Inbound and Outbound mail traffic. However, the client has reported an issue that they're experiencing emails showing twice in the Office365 logs , double signatures and random internal emails going into spam/junk within the users mailbox. We have checked the internet message headers for those emails (in the spam/junk folder) and checked the a header of X-Forefront-Antispam-Report and all of them were SFV:NSPM which means that the message was marked as non-spam and was sent to the intended recipients !! The client has contacted Microsoft to resolve the issue,however, Microsoft got back to the client and they can’t find any relevant information on why the emails are going to spam/junk folder. Could you please help to identify and resolve this issue, please?

Thanks for your reply! I've followed your advice on the previous reply. So, I disabled Spam Quarantine on ESA and enabled it on SMA with Spam Notifications, and I can see new messages in the Spam Quarantine now! Thanks once again !

Thanks for your reply! We have noticed that we haven't had Spam Quarantine Notifications since last week, although Spam Quarantine & Spam Notification are enabled on both ESA & SMA. What could be the reason for that? could it be because we configure Spam Quarantine & Spam Notification on both C100V & M100V ?

Hi there, We have configured our CES for Content Filter to block attachment files and q uarantine the email addresses and we have enabled Quarantine Notification to be sent from spaminfo@mydomin.com to all recipients, however, the Quarantine Notification always comes form this email address :noreply@ces.cisco.com How can I change this default email address to the one I have configured? Also, even though we didn't enable "Enable End-User Quarantine Access" on both ESA (C100V) and SMA (M100V), the user still able to release the quarantined email, how can we disable that. Is configuring Spam Notification on both C100V & M100V correct setup? Thanks!

Hi there, I'm new to SG series , so hope someone can direct/guide me on how to configure SSH on SG-550X switch to allow only access from specific IP addresses. I know how do do that on Cisco IOS with ACLs, but not on SG-550X since there are different entries for " SSH server authentication" and "SSH user authentication" I even can't type line vty 0 4. Is there a way to replicate these commands below in SG-550: | access-list 10 permit 192.168.1.0 0.0.0.255 SW(config)# line vty 0 4 SW(config-line)# password ciscovtypass SW(config-line)# login local SW(config-line)#transport input ssh SW(config-line)#access-class 10 in Thanks

Sorry Giuseppe, Do I need to enable DHCP Snooping as well or just DHCP Relay?

Hi! I tried what you suggest " Each switch should have a single physical link to each firewall. Links to Drake in Vlan 16 on both switches. Links to Barracuda in Vlan 17 in both switches." unfortunately it gives error that " ERROR: Name "inside" has been assigned to interface GigabitEthernet0/0 DrayeTek-FW(config-if)# ip address 172.16.1.4 255.255.255.0 ERROR: Failed to apply IP address to interface GigabitEthernet0/1, as the network overlaps with interface GigabitEthernet0/0. Two interfaces cannot be in the same subnet."

Hi there, I tried to do the VRRP to the FWs, but it gives me error on the firewall "ERROR: Name "inside" has been assigned to interface GigabitEthernet0/0 DrayeTek-FW(config-if)# ip address 172.16.1.4 255.255.255.0 ERROR: Failed to apply IP address to interface GigabitEthernet0/1, as the network overlaps with interface GigabitEthernet0/0. Two interfaces cannot be in the same subnet." Is this the correct design to set up VRRP for VLAN 16 & 17 which connect to 2 FWs? for some reason it's not working for me

We have a Small-medium-sized client who has flat network ( VLAN 1) for everything (Phones, Servers and PCs) And they have remote sites which uses VPN to connect to their HQ. They want to use different VLANs for Phones, DATA and Servers. So they got two cisco SG550X as core switches as shown in the diagram below .. I've got few questions about the design below if someone could help : 1) First regarding VRRP: I will configure it for VLAN 1,2 and 3, Can I do it for VLAN 16 & 17 ( connecting to FWs)? or it's not recommended? 2) Do I need to connect the core switches (SW-Core1-550 & SW-CORE2-550 ) together (uplink)? 3) As you can see in the diagram, the two core switches are connected to one access switch (1gig switch), is it better to split the connection into two access switch instead of one? 4) Is it better to connect Netgear switch (10gig switch) to the two core switches instead of the (1gig) HPE access switch? 5) As in the old design they have only default VLAN1, now with new design we need to create all VLANs in all access switches and configure all uplinks between switches as trunk...is that right? 6)As you can see the AVAYA IP Office manager (Server) is in different subnet (192.168.50.9) than phone VLAN (192.168.2.0/24) Will the phone devices be able to reach the call manger to register? Note: IP routing is enabled on the core switches. -DHCP Relay/IP helper is enabled on the core switches. -Windows server( 192.168.50.2) is used as DHCP Server.(created 3 DHCP Scopes for the 3 VLANs with required option for AVAYA)
